257680 ÷ 71 
Let's see how many times 71 fits into 257680.

Going ahead to step 1:
When dividing 2 by 71, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 71

Going ahead to step 2:
71 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 71

Going ahead to step 3:
71 goes into 257 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 44 after subtracting 213 from 257.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 71

Advancing to step 4:
71 can be fit into 446 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 20 after subtracting 426 from 446.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 71

Step 5:
If we divide 208 by 71, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
Subtracting 142 from 208 leaves us with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 71

On to step 6:
The number 71 fits into 660 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 3629.0
If we subtract 639 from 660, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 71, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 3629.2
Subtract 142 from 210 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
680 divided by 71 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 3629.29
Deduct 639 from 680 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
If we divide 410 by 71, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 3629.295
If we take 355 away from 410, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
The number 71 fits into 550 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 3629.2957
The remainder is 53 after subtracting 497 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
530 divided by 71 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 3629.29577
The remainder is 33 after subtracting 497 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 3629.29577, with a leftover of 3.3e-05.
